@if/725W@ platform 4 and through a bear-ing 29 arranged at the rear face of the cross piece 19. This bearing prevents the shaft 28 from turning with relation to the platform. The shaft 28 is provided with a lower detachable section. 30 which carries the cutting auger 29, the section 30 being provided 'in its upper end with a socket 3l to receive the lower reduced end 32 of thelupper or main section 33 of the shaft, the sections 30 and 33 being det-achably connected together yby the transverse connecting pin 34, By this construction the lowersection carrying the cutting auger may be removed for sharpening or e different sizesv of cutting augers may be used without removing the shafting proper. The

-A scoop or bucket 35 which is of approxi- `top of the section 36 and bear against opposite faces of the shaft 28. As showin the boxing 38 iits the shaft 2S loosely while the bearing'rollers 39 hold the scoop or bucket against vibratory movement as it is raised or lowered. i

'Ihe sections 3G and 37 of the scoop or bucket are provided at their bottoms with the downwardly and oppositely inclined scoops 41 and 42 which scoop up the loosvvened dirt into the bucket as it is revolved.

The section 37 is provided at its top .with an arcuate arm 43 provided with vthe vertical opening 44 which registers with a corresponding opening 45 in the top of section 36 to provide for the insertion of a securing pin 4G for holding the sections closed. A

hoisting cable 47 windsupon the drum 23 and after passing upwardly over a pulley 48 mounted in a bearing bracket 49 a1'- ranged upon the cross piece 19, passes downwardly and is connected in any substantial mannerwith the top of the scoop or bucket. A second cable 50 winds upon the other drum 27 and'after passing upwardly over the pulley 51 also mounted in the bearing 49 passes downwardly throughthe tubing 52 formed on the boxing 3S of section 36 of the scoop or bucket and is connected as at 53 with the lower section of the shaft of the cutting auger. The lower end of the cutting auger shaft is coupled with the pla'tf form 4 bymeans of the coupling bar 54 which is pivoted at'one endin the bearing 55 and extends across a central opening'56 in the platform of sufficient size to receive the scoop or bucket- 35. The free end of the coupling bar 54,when swung down, fits between a pair of vertical lugs 57 rising -from the platform while the coupling bar is provided with a central approximately U-shaped portion 58 to receive the shaft, said portion 5S being provided withl a pair of bearing rollers 59 which bear against opposite faces of said. shaft. By this means the lowervend of the cutting auger shaft is coupled with the platform so that when the, platform is turned. the shaft is turned with it. f

ln the operation of the device the plat form 4 is rotated by a draft animal which is hitched to the single tree 60 of the carrying bar 61 'connected with theA platform. AAsthe plat-form is rotated the cutting auger and shaft is also rotated and cuts into the ground. After the cutting auger has cut to the depth of, say, two feetthe scoop or bucket. 35 is allowed to descend upon the shaft on `the loosened dirt. After the scoop or bucket is filled'with, dirt the winding drum 23 is thrown into gear by pulling down upon the free end of thev clutch lever 62 to throw the clutch member `63 carriedA thereby into engagement with the clutch 7 of the pinion The scoopj-or bucketis then caused to ascend upon the shaft 28.

Before the bucket reaches lthe coupling bar 54 the latter is swung into an approximately vertical position to permit the bucket to, pass,vwhi'le the crank 64 on the end of the shaft 15 is turned in'` order to slightly raise the cutting auger and. thus throw it out of operation, while the coupling 54 is not in engagement with the shaft 28. This is done for the reason that` the shaft 28 may not be capable of withstanding the excessive twisting strain exerted thereon while the coupling 54 is disengaged therewith. The scoop or bucket 35 ascends upon the shaft 28 until it strikes the linner end of the trip 65 lpivoted intermediately of its ends to a bracket 66 depending from the cross piece 19. The outer end of the tri bar 65 is -pivotally connected with the trip ar 67 which is piv oted tothe bracket 68 and is connected at its'outer end by means of the cord or cable 69 with the clutch carrying lever 62. When the bucket strikes the trip bar 65 as is heretoforev stated the outer end of bar 67 is swung up and through the medium' of the cable 69 raises the free end of the clutch carrying. lever 62 which disconnects the clutch member 63 with clutch member -7 of pinion 5 and throws the winding drum' 23 out of operation.. When the scoop or bucket .reaches the limit of its upward sliding movementl upon the shaft 28, it is engaged by the hooked end 70 'of the catch 71 pivoted at the junction of its arms in the bearing 49, the arm 72 of the catch carrying the Weight 73A which holds the hook 70 against l accidental disengagement with the scoop or bucket. e

Th'e'bucket having been raised and 'engaged as above described, the dumping car 74, which is mounted upon a suitable track .isa

and means of connection between the trip device and the bucket raising mechanism,

'whereby the latter is thrown out of gear when the former is trip ed by the bucket.

` S cessed portion 7 6, at the opposite end of thc car from the hinged door 77, receives ltheshaft 28.Y The section 37 of` the bucket 35, is then swung from'the section 36. The outerfends of the rails lof the track 7g3', project beyond l the rear side .of the platform and terminate I in upwardlyrprojecting outwardly inclined' stop guards78, provided at their lower endsA with the semi-circular portion 79. VThe outer end wall 77 of the ear body is held in closed position by the catch 80 ivoted, as at 81,

to one side of the car bo y. An operatingI link or lever 82, is connected with thecatch by means ofv whichthe catch may be disengaged .from the ,hinged door 77 whenever 2 0 desired: 'When the dumping car is filled with dirt, .it is pushed to the ,outer end of the track'while the releasing vlink is pulled upon at the same time todise'ngage the catch 8O from the door 77. The car, upon reaching the outer end of the track is caused to tilt up in the position indicated inthe draw ings and deposits the dirtV upon the ground `or into a suitable car or other vehicle which may -be arranged to receive the same.I fVVhen it is desired to fill the scoop or bucket 35,' a "second time, it is released and permitted to descend upon the shaft 28, the 'speed at which'said bucket descendsbeing controlled -by a hand'brake consisting of the U-shaped brake-shoeSl pivoted at its upper end to one e of lthe vertical members 1Sa'nd loosely lcon-v nected at its lower end, 'as ,at 85,- to thevertical extension 86 of the horizontal operating lever l87, pivoted intermediately of its ends '40 as at 88, to the vertical member 18, just re- I ferred to beneath the lower end of the brake# shoe and providedl at its pivoted end with' a weight 89 to normallyhold the brake lshoe out of engagement-with the winding drum 23.
